Problems solved by technology

[0005] The present invention uses a temperature sensor to measure the ambient temperature. When the ambient temperature is lower than the lower limit of the normal operating temperature of the crankcase ventilation system, the controller outputs a control signal to connect the first relay, so that the ventil

Embodiment Construction

[0016] Such as figure 1 As shown, the crankcase ventilation and heating system of the present invention is composed of a ventilation outlet heater 1, an oil-gas separator heater 2, a temperature sensor 8, a speed sensor 9, a first relay 10, a second relay 11 and a controller 4. The controller can be the CPU inside the vehicle-mounted computer ECU, or other microprocessors. Ventilation air outlet heater 1 is installed and fixed between the intake hose 5 and the air outlet pipe 6 of the crankcase by a clip, and the oil-gas separator heater 2 is installed and fixed on the crankcase oil-gas separator 7 by a clip. Ventilation outlet heater 1 is connected to controller 4 through heating harness 12 and first relay 10 ; oil-gas separator heater 2 is connected to controller 4 through heating harness 13 and second relay 11 . The temperature sensor 8 is installed on the vehicle body. The speed sensor 9 is a photoelectric encoder, which is installed on the engine output shaft. Temperat...

Abstract

The invention relates to a ventilating and heating system of a crankcase, which comprises a ventilation gas outlet heater, a controller, a temperature sensor and a first relay, wherein the ventilation gas outlet heater is fixedly arranged between a gas inlet hose and a gas outlet pipe of a crankcase, and the temperature sensor is fixedly arranged on a vehicle body; the temperature sensor is used for converting the measured environment temperature into an electrical signal and transmitting the electrical signal to the controller, and the controller is used for judging whether the environment temperature is lower than the normal working temperature lower limit of the crankcase according to the electrical signal, and outputs a control signal to be connected with the first relay if the environmental temperature is lower than the normal working temperature lower limit of the crankcase to ensure that the ventilation gas outlet heater starts working. The ventilating and heating system of the crankcase solves the problem of cold region freezing of the engine crankcase ventilating system, and ensures the reliability when a vehicle is used in an extremely cold area. The ventilating and heating system of the crankcase has a simple structure, and brings convenience for arrangement.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a crankcase ventilation and heating system. Background technique [0002] The crankcase ventilation system is one of the important components of the engine. Its main function is to reasonably control the crankcase pressure; separate the oil and gas in the crankcase discharge, and return the separated oil to the oil pan. Because the crankcase gas contains a lot of water, the crankcase ventilation system of the vehicle working in the cold area will often be blocked due to freezing, causing oil leakage at the seal, and eventually causing the engine to be scrapped. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a crankcase ventilation heating system capable of avoiding freezing of the vehicle crankcase ventilation system and ensuring the reliability of the vehicle when used in extremely cold regions. [0004] The cran...
